Answer:
Y= $240
Step-by-step explanation:
Since he had 60 dollar bills and the dollar coins were 4 times that amount, you just multiply 60 by 4.
Permutations are written as nPx where n is the number of total choices possible and x is the number of choices that will be used. This is calculated as nPx = n! / (n-x)!.
Permutations represent the number of ways we can choose x objects from n possibilities where the order of selection matters.
Answer:
Step-by-step explanation:
We can solve this with the help of Pythagoras theorem.
- => (√50)² = x² + x²
- => √50 x √50 = x² + x²
- => 50 = 2x²
- => 25 = x²
- => x = 5
Hence, the value of x is 5 units.
Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that
. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have
. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides
as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
